This is the README.txt file for the NAG Fortran Compiler Release 7.1. 1. Installation Installation instructions and requirements are provided in the file TECHINFO.txt. The installation may be tested by compiling and running the utility program f90_util.f90, which is provided in the same directory as the compiler library files. To compile and link this program, copy the source file to your working directory and type nagfor -o f90_util f90_util.f90 (This assumes that the compiler binaries have been installed in a directory included in your PATH environment variable.) The program (f90_util) may now be run. 2. Licensing The NAG Fortran Compiler is a licence-managed product using Kusari.
